Indiana Underwater: ‘Catastrophic’ Flooding Follows Brutal Midwest Storms
Monster Storms Drown the Midwest: What You Need to Know About the Historic Flooding
The Big Picture: A Week of Wild Weather
Imagine a garden hose left running on full blast for days—that’s basically what Mother Nature has been doing to the Midwest since Sunday. A relentless parade of storms has been pounding the region, and they’re not planning to leave until Friday at the earliest.
The hardest hit? Indiana. On Wednesday, the state got more than three months’ worth of rain in just 36 hours. That’s not a typo—entire towns are underwater, roads have washed away, and the governor is preparing a statewide emergency declaration.
Important: If you’re in the affected areas, stay off the roads and follow local evacuation orders immediately. Flash flooding can turn deadly in minutes.
What Happened in Indiana: By the Numbers
Rainfall That Breaks Records
- New Castle got over 11 inches of rain in 32 hours — that’s a "1-in-1,000-year flood event" (only a 0.1% chance in any given year)
- Eastern Indiana received 3+ months of normal rainfall in 1.5 days
- Rainfall rates reached up to 3 inches per hour in some spots
Towns Under Water
| Location | Situation |
|---|---|
| Cambridge City | "Catastrophic" flooding — water past house windows, cars nearly submerged, boil-water advisory in effect |
| Muncie | Door-to-door evacuations of ~200 homes, 12+ boat rescues, first day of school canceled |
| New Castle | Waist-deep floodwater, city buses used to evacuate residents to shelters |
| 7 Eastern Counties | Under Flash Flood Emergency — the highest, most urgent warning level |
Power & Infrastructure Crisis
- Nearly 300,000 homes and businesses without power in Indiana alone
- Multiple roads completely washed out (see video below)
- One utility company reported its largest outage event in history

Tuesday’s Deadly Derecho: What Is That?
Before Wednesday’s floods, Tuesday brought a "derecho" — a scary weather word you should know.
ELI5 Definition: A derecho (deh-RAY-cho) is like a hurricane made of straight-line wind instead of spinning wind. It travels fast, lasts a long time, and leaves a massive path of destruction — sometimes hundreds of miles long.
Tuesday’s Toll:
- 4-year-old boy killed in Geneva Township, IN when a tree crushed a house
- 1 death in Portage, IN from apparent gas explosion/fire after trees fell on gas lines
- 1 death in Ohio — emergency responders couldn’t reach the person due to flooding
- 16 inmates hospitalized in Ohio after lightning struck a correctional facility (7 still hospitalized)
Ohio Gets Slammed Too
Ohio didn’t escape — Governor Mike DeWine declared a state of emergency for Perry and Muskingum counties and activated National Guard high-water rescue teams.
Why Is This Happening? (The Climate Connection)
You might be wondering: "Is this normal?" The short answer: No — but it’s becoming the new normal.
Simple Science: Warmer air acts like a bigger sponge — it holds more moisture. When storms come along, they wring out that sponge, dumping way more rain than they used to.
Scientists say these "1-in-1,000-year" floods are happening more often because of fossil fuel pollution warming the planet.
What’s Coming Next: The Forecast
Thursday
- High flood risk continues for Illinois, Indiana, and Ohio
- 4+ river gauges in eastern Indiana forecast to hit major flood stage
- Northern Kentucky upgraded to Level 3 of 4 flood risk
Friday
- Storms may finally ease
- Flood threat shifts north to Upper Mississippi Valley
- Some lingering showers possible in Ohio Valley and Appalachians
Wednesday Evening
- Severe storm risk remains for parts of Ohio Valley
- Damaging winds possible (but not as bad as Tuesday’s derecho)
- More power outages and downed trees likely
How to Stay Safe: Your Action Plan
1. Right Now — If You’re in the Danger Zone
- Evacuate immediately if told to do so
- Never drive through flooded roads — 12 inches of water can float a car
- Get to higher ground if you see water rising
- Monitor local news and the CNN Weather App for real-time alerts
2. If You’re Safe at Home
- Charge all devices now (power may go out)
- Fill bathtubs/sinks with clean water
- Check on neighbors — especially elderly or disabled
- Have flashlights, batteries, and a battery-powered radio ready
3. After the Water Recedes
- Don’t enter flooded buildings until cleared by officials
- Don’t use flooded electrical outlets or appliances
- Boil water if under advisory (like Cambridge City)
- Document damage with photos for insurance
- Watch for mold — it grows fast in damp conditions
Summary: Key Takeaways
| What Happened | Why It Matters |
|---|---|
| Historic rainfall (11+ inches in 32 hrs) | "1-in-1,000-year" event — but happening more often |
| Multiple towns underwater | Homes, roads, schools, utilities destroyed |
| 3+ deaths so far | Tree falls, gas explosion, inaccessible emergencies |
| 300,000+ without power | Largest outage in utility company history |
| Storms continue through Friday | More flooding, more danger ahead |
| Climate change link | Warmer air = wetter, more destructive storms |
Frequently Asked Questions
What exactly is a "Flash Flood Emergency"?
It’s the highest, most urgent flood warning the National Weather Service issues. It means catastrophic, life-threatening flooding is happening RIGHT NOW — not "might happen." Immediate action is required.
How much water does it take to float a car?
Just 12 inches (1 foot) of moving water can float a small car. 2 feet can sweep away most vehicles, including SUVs and trucks. Turn around, don’t drown.
What’s the difference between a derecho and a tornado?
- Tornado: Spinning wind, narrow path, very high wind speeds in a small area
- Derecho: Straight-line wind, hundreds of miles wide, lasts hours, destroys everything in a broad path
Both are extremely dangerous.
Why are these "rare" floods happening so often now?
Because the baseline has shifted. A warmer atmosphere holds ~7% more moisture per degree Celsius of warming. Storms today have more "fuel" (water vapor) than storms 50 years ago, so they produce heavier downpours.
When will this finally stop?
Forecasters say the main threat eases by Friday, but rivers will stay high for days after the rain stops. Some areas could see flooding into the weekend as water drains downstream.
Final Thought
This isn’t just "bad weather" — it’s a glimpse of our climate future. The Midwest’s "1-in-1,000-year" flood is becoming a "1-in-20-year" flood. Preparing now — better drainage, smarter building, emergency plans — saves lives later.
Stay safe, stay informed, and look out for each other.
